IPC: F23J13/00
Filed: 1985-05-21
Abstract: A flue pipe assembly for use within or, as shown, at the outlet of a chimney stack comprises an inner pipe (7), e.g. of fire clay material, and an outer pipe (8), e.g. of stainless steel, between which is mounted an expansion accommodating member (10), e.g. of corrugated aluminium, to accommodate expansion and contraction of the inner pipe (7) within the structural member, e.g. stack coping, in which the assembly is mounted. A top pipe (11) of fire clay material may be mounted on the outer pipe (8) to prevent the penetration of rain and moisture into the gap between the pipes (7) and (8), or the inner pipe may be extended beyond the outer pipe and flanged to cover the gap. The outer pipe (8) may alternatively be of fireclay or asbestos, and the member (9) could be of fibreglass or plastics. <IMAGE>

Title: A process for the fast cold dyeing of textile materials
Inventor: PERNETTI CLAUDIO
IPC: D06P1/00
Filed: 1985-06-10
Abstract: A process for short duration dyeing textile materials at low temperatures, useful for dyeing carpets, is characterized by the following combination of features:   (a) the use of a term of dyestuffs which produce in the textile material being dyed a significantly constant shade and a decrease in luminosity which is sufficiently slow and allows a homogeneous uptake of the dyestuff on the textile material during the whole dyeing process; (b) maintenance of an alkaline pH which decreases gradually, during the process, down to neutrality;   (c) maintenance of a maximum temperature below 40 DEG C;   (d) a duration shorter than or equal to 150 minutes.   Perfect dyeing uniformity is achieved through the use of conventional equipment of the art.

Patent GB-2178203-A (GB)
Title: Regulating electron beam emission
Inventor: MALONE HOWARD F
IPC: H05G1/34
Filed: 1986-06-24
Abstract: A system for regulating the electron beam emission of an accelerator has a filament whose temperature is controlled by pulse width modulation of the current flowing to the filament (8). A variable impedance transformer (4) serially connected between the filament and RF power source (4) is electronically switched between high and low impedance at a rate faster than the thermal time constant of the filament whereby the variations of current flowing in the filament are averaged by the thermal response time of the filament so that the temperature and electron emission level of the filament remain substantially constant. The impedance switching signal is generated in response to changes in current flowing in the high voltage coils of the accelerator. The pulse width can be modulated over a wide range to vary the electron current over a range greater than 2:1. The switching signal is transmitted across the high voltage gradient of the accelerator by an optical link including an LED coupled to a phototransistor (15) by a light pipe (16). <IMAGE>

Title: Continual feed of insulated core
Inventor: HOOPER LENNARD
IPC: B65H49/12
Filed: 1988-12-17
Abstract: A communications cable can be continuously manufactured by drawing the cable elements from primary bobbins (1A to 1U) the tails of the bobbins being connected to the leading ends of elements on a corresponding set of secondary bobbins (2) so that automatic changeover of feed from one bobbin to the other occurs. When the apparatus is set up each primary bobbin has a different length of element wound on it so that the joints in the element between the primary and secondary bobbins will be longitudinally spaced along the length of the cable. It is found that in the case of a twisted copper pair cable, the change in twist produced by drawing the copper pair from a continually changing diameter on the bobbin as it unwinds produces a substantially random twist variation throughout the cable which is beneficial to minimising cross-talk. <IMAGE>
